The I Ching (pronounced "E Jing") is one of the oldest known books in human history and translates to "The Book of Changes". While many use this book for divination, that was not its original purpose. It is an observation of nature and the different ways in which it exists and changes. This is a difficult read and very symbolic. My favorite translation is by Hua-Ching Ni and can be found on Amazon at www.amazon.com. There are many translations widely available and a free PDF version can be found at http://elibrary.ibc.ac.th/files/private/The%20Buddhist%20I%20Ching.pdf
